But tragically, on the day of a hockey game, she deliberately took more than her prescribed dose of medication for Raynaud’s - a condition which causes numbness and pain in the joints, fingers and toes.

After collapsing at the Southlands Leisure Centre in Middlesbrough , she was taken by ambulance to the town’s James Cook University Hospital, where she went into cardiac arrest.

But despite concerted attempts to save her, lasting several hours, she died later that evening.

A post mortem gave the medical cause of death as hydroxychloroquine toxicity - the medication she used, with intermittent success, to treat her Raynaud’s, which could cause pains and swelling in her limbs, joints, hands, arms and face.

The inquest heard Holly, who was born in Winchester but lived in Eaglescliffe , was studying an outdoor pursuits BTEC course at East Durham College, was successfully accumulating UCAS points to get to university to do a sports science degree, had a “quiet, kind and gentle” boyfriend and was excelling in sport.

Described by parents Andrew and Melanie as “a big personality” who “loved partying with her friends”, her “greatest passion” was sailing, and she had recently attended the prestigious Scottish Keelboat Academy.

But she was also a keen hockey player and played for Norton Hockey Club, where she was a youth coach and first team player.

In short, as Teesside Senior Coroner Clare Bailey observed, she was “in a very good place.”

Tragically, however, she collapsed at the Southlands Centre, where she’d gone for a hockey game.

A statement from paramedic Kevin Cook said a North East Ambulance Service team attended the centre on November 20 after reports a young woman had collapsed. With a hockey game going on, they found Holly lying on the floor, having been placed in the recovery position.

After treatment, during which she was conscious for some of the time, she was put into the ambulance and taken to James Cook University Hospital.

Mr Cook’s statement said Holly said she needed to speak to someone in private about something she didn’t want anyone to know.

A colleague said Holly had told him she’d taken an overdose of tablets.

However, the inquest heard, a police investigation said there were no suspicious circumstances surrounding her death, and that they had formed the opinion that Holly had taken the medication to try and reduce the pain she was feeling in order to play hockey that night.

A statement from Mr and Mrs Monk, read out at the inquest, said: “The possibility she was trying to end her life seems nonsensical to us as so many things were going right in her life.”

The coroner asked Mr Monk whether her condition interfered with her sailing and hockey. He replied: “It did, but she would just keep going.”

As well as her Raynauld’s, Mr Monk had also raised the possibility Holly may have had the tick-born condition Lymes Disease, as some of her symptoms seemed to fit. However a doctor at Newcastle’s Royal Victoria Infirmary said Holly wasn’t tested for it and hadn’t raised suspicions of her having it.

Concluding the inquest, Ms Bailey said: “It would appear there was no reason for Holly to take her own life. She was in a very good place.

“She told a paramedic she hadn’t intended to take her own life. The police are also satisfied she took the medication to try and ease her pain so she could play hockey.”

She then asked Holly’s parents: “Do you think she took the medication so she could continue to play hockey?” Mr Monk replied: “Yes.”
